Detailed Product Description

PRODUCT DESCRIPTION
nano calcium carbonate -203 is a surface treated, super ultrafine and very narrow particle size distribution precipitated calcium carbonate specially formulated as functional additive in oil paint.
  
APPLICATIONS

nano calcium carbonate -203 can make coatings diluted rapidly under high shear situation, and the viscosity will be recovered quickly once external force withdrawn. With NPCC, the coating has many outstanding functions such as excellent adhesion, impact and scratch resistance, strong and durable property, whats more, it is easily to realize high speed production.
